Link Alert - What happens when you click on a link? Are you going to open a new window? download a file? read a document? Now you’ll be able to quickly find that out. By simply hovering your mouse over the link, your cursor will change to indicate what will happen next.

Tab Mix Plus - Even with Firefox 2.0’s improved tabs, this extension is still powerful. Aside from enabling you to do just about anything with your tabs, I love that it incorporates a session saver where you can save all your tabs for later use.

Download Them All - DownThemAll is the ultimate downloads manager. It features an advanced accelerator that increases speed up to 400% and it allows you to pause and resume downloads at any time.

Stop-Or-Reload Button - You either stop loading a page, or you reload a stopped one. You only really need one button. This extension merges them both and saves you screen space.
